Detecting overlap

I have code now, thanks to IdleMind that allows me to drag a Picture Box around on a form.



I have another PictureBox on the form.


When I stop dragging the PictureBox...I want to be able to detect if the border of the one PictureBox  is overlapping the border of other PictureBox.




My current code should work with a new C# Windows App project, for that is what I am using to test these concepts with.




using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;

namespace WindowsApplication2
{
      /// <summary>
      /// Summary description for Form1.
      /// </summary>
      public class Form1 : System.Windows.Forms.Form
      {
            private System.Windows.Forms.PictureBox pictureBox1;
            private System.Windows.Forms.PictureBox pictureBox2;
            /// <summary>
            /// Required designer variable.
            /// </summary>
            private System.ComponentModel.Container components = null;

            private int startX, startY;

            public Form1()
            {
                  //
                  // Required for Windows Form Designer support
                  //
                  InitializeComponent();

                  //
                  // TODO: Add any constructor code after InitializeComponent call
                  //
            }

            /// <summary>
            /// Clean up any resources being used.
            /// </summary>
            protected override void Dispose( bool disposing )
            {
                  if( disposing )
                  {
                        if (components != null)
                        {
                              components.Dispose();
                        }
                  }
                  base.Dispose( disposing );
            }

            #region Windows Form Designer generated code

Try...

        int startX, startY;

        private void pictureBox1_MouseDown(object sender, MouseEventArgs e)
        {
            if (e.Button == MouseButtons.Left)
            {
                startX = e.X;
                startY = e.Y;
            }
        }

        private void pictureBox1_MouseMove(object sender, MouseEventArgs e)
        {
            if (e.Button == MouseButtons.Left)
            {
                pictureBox1.Location = new Point(pictureBox1.Left + e.X - startX, pictureBox1.Top + e.Y - startY);
            }
        }

        private void pictureBox1_MouseUp(object sender, MouseEventArgs e)
        {
            if (e.Button == MouseButtons.Left)
            {
                Rectangle pb1 = new Rectangle(pictureBox1.Location, pictureBox1.Size);
                Rectangle pb2 = new Rectangle(pictureBox2.Location, pictureBox2.Size);
                if (pb1.IntersectsWith(pb2))
                {
                    MessageBox.Show("Overlapping");
                }
                else
                {
                    MessageBox.Show("NOT Overlapping");
                }
            }
